Gaz

Gaz is a short form of the English name Gareth or, less commonly, Gary, both of which have distinct origins: Gareth is likely derived from a Welsh form of an Old French name meaning enclosure or protection, while Gary traces to an Old English or Germanic element meaning spear. As an independent given name, Gaz is largely informal and chiefly found in British and Australian usage, functioning as a colloquial nickname rather than a formally registered name. It shares its informal register with other clipped forms such as Gazza, famously associated with English footballer Paul Gascoigne.
